Research

Research themes, lab affiliations, and collaborations in speech signal processing and speech technology.

Research themes

Speech Signal Processing

Analysis of the speech signal and of the voice source itself: estimating how the glottis opens and closes, separating source from filter, and characterising voice quality.

  • Glottal closure and opening instants
  • Glottal inverse filtering
  • Voice quality

Speech, Health and Cognitive State

Using acoustic and voice-source features to study how cognitive load and mental health conditions are reflected in speech.

  • Cognitive workload in speech
  • Depression and anxiety in speech

Speech Recognition and Synthesis

Recognition and synthesis methods that work for languages with limited data and resources, with Icelandic as the primary case.

  • Speech recognition with limited resources
  • Speech vocoding
  • Text-to-speech synthesis for Icelandic
  • Speech recognition for Icelandic

Labs and affiliations

Language and Voice Lab

Research group at Reykjavik University working on speech and language technology for Icelandic.

Icelandic Language Resources

Open datasets, models and tools supporting Icelandic language technology.
